Gui script will not work online mode?

I tried making a script where when you hover over a gui it the players camera moves. It works perfectly but the problem is only in offline mode "Play solo". I'm not sure how to fix it

varMax = 20
varCamMove = 0
varMax2 = 5
varCamMove2 = 0


cam = game.Workspace.CurrentCamera

script.Parent.AA.MouseLeave:connect(function(x, y) 

    varCamMove = 0  

end)

script.Parent.AA.MouseEnter:connect(function(x, y)

    varCamMove = 1

while varCamMove == 1 and varMax <50 do
    wait()

local cam_rot = cam.CoordinateFrame - cam.CoordinateFrame.p
local cam_scroll = (cam.CoordinateFrame.p - cam.Focus.p).magnitude
local ncf = CFrame.new(cam.Focus.p)*cam_rot*CFrame.fromEulerAnglesXYZ(10, 5, 0)
varMax = varMax+1

cam.CoordinateFrame = ncf*CFrame.new(0, 0, cam_scroll)

print  ("CamrotateRight" ..varMax.. "")

end
end)

script.Parent.Left.MouseLeave:connect(function(x, y) 

    varCamMove = 0  

end)

script.Parent.Left.MouseEnter:connect(function(x, y)

varCamMove = 1  

while varCamMove == 1 and varMax >5 do
    wait()

local cam_rot = cam.CoordinateFrame - cam.CoordinateFrame.p
local cam_scroll = (cam.CoordinateFrame.p - cam.Focus.p).magnitude
local ncf = CFrame.new(cam.Focus.p)*cam_rot*CFrame.fromEulerAnglesXYZ(10, 0, 5)
varMax = varMax-1
cam.CoordinateFrame = ncf*CFrame.new(0, 0, cam_scroll)

print  ("CamrotateLeft" ..varMax.. "")

--{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}--



end
end)

Thanks, Exsius.
